The Wilson Combat Match Grade Barrel in .300 Blackout, 16 inches (brand part no. TR300RCPG16RT7), gives AR-15 builders a stainless steel barrel machined to the same exacting standards Wilson Combat applies to its complete rifles. Cut from American-made 416R rifle-rated steel on computer-controlled equipment, it features a hand-polished bore and feed ramps, crisp CNC markings, and a precision-cut muzzle crown for consistent accuracy shot after shot. The pistol-length gas system and 1:7 twist rate suit the wide range of .300 Blackout bullet weights, from lightweight supersonic loads to heavy subsonic rounds, and the barrel ships threaded and finished in a stainless bead-blasted surface. Wilson Combat also optimizes the chamber and gas port for reliable cycling across ammunition types.
